Abstract: An apparatus and method of compensating for disturbances using learning control is provided. An optical recording medium drive servo system of an optical recording/reproducing apparatus, the system including an actuator for moving the position of a head for recording data on a recording medium or reproducing the recorded data from the recording medium, an error detector for detecting the difference between the reference position on the recording medium and the actual position of the head, that is, a position error, a compensator for receiving a value from the error detector and producing a value for driving the actuator, a first memory for storing a control input for compensating for the position error of the actuator due to a periodic disturbance such as eccentricity, a second memory for converting the content of the first memory according to phase and storing the converted content, a timing controller for generating addresses for the first memory and addresses for the second memory according to phase, and an adder for applying the content of the first or second memory together with the output of the compensator to the actuator. Accordingly, a periodic disturbance component including the eccentricity can be rapidly and effectively compensated for using a previously-learned control result regardless of a variation in cycle such as a variation in the speed of a spindle due to a variation in the reproduction speed of a recording medium.

Abstract: In the convention, although bifid bacteria, oligosaccharides, antibiotics, etc. as the feed additive are used, the improvement of the amount of the body growth and the demand for the feed, etc. could not been expected. Also, if antibiotics are used for the therapy of the diseases, that will be a violation of the Drugs, Cosmetics and Medical Instruments Act, and when they are given to the livestock or the fish, there are some cases that the feed is excreted in an undigested state, and thus the bad smell is given off and caused a problem of the environmental pollution in the case of the livestock. The present invention relates to a feed additive for the livestock and the like, characterized in that, the first feed additive prepared by mixing and pickling 50-80% by weight of ume (Japanese apricot) as a main ingredient, 1-3% by weight of shochu (Japanese distilled spirits) as a quality-improving agent, 18-45% by weight of sugar and 1-4% by weight of other additives such as vitamins for a predetermined period and the second feed additive prepared by mixing and pickling 65-85% by weight of ume as a main ingredient and 15-35% by weight of salt for a predetermined period are mixed in a ratio of about 1:1 and then 0.3-0.7% weight thereof is added to the feed.

Abstract: A driving apparatus has a roller screw member that includes a main shaft, a plurality of roller shafts projecting radially outwardly and upwardly at an angle from the radial direction of the main shaft and arranged along a helical line there around, and a plurality of rollers rotatably mounted on the roller shafts. The rollers are tapered to the same angle inwardly toward the main shaft. A rail member, adjacent to and axially oriented with the main shaft, includes a plurality of spaced projections adapted for radial engagement with the tapered rollers. The angle of the tapering is pre-determined to provide a sliding free engagement between the rollers and the projections with the interface there between being oriented to intersect the rotation axis of their respective roller shaft on the rotation axis of the main shaft. The rotation of the main shaft axially moves the roller screw relative to the rail member.

Abstract: A horizontally rotating apparatus for longitudinal positioning of lumber pieces in length trimming. The system functions alongside a parallel chain transfer conveyor which moves the lumber laterally towards a multiple saw trimmer, all pieces being evenly spaced and aligned endwise to one side of the chain transfer, as is customary in trimmer feed systems. The apparatus comprises one or a number of evenly spaced clamping devices rotating about a vertical axis and describing a circular path which slightly overlaps the even end line of the incoming lumber. Upon closing on the end portion of a board in the overlapping zone, the clamp pulls it along the established arc of rotation, firstly in a direction mostly parallel to the original lumber travel and, secondly, in a progressively perpendicular direction, as the rotation of the clamp continues. The clamp opening and subsequent release of the piece are controlled by computer command according to scanning data obtained for each piece, thus performing a basic positioning operation to be refined, for certain operating conditions, by adding an independently controlled locating bar accessory.

Abstract: The invention relates to a method and an apparatus for heating glass panels in a tempering furnace equipped with rollers. Glass panels (7) are carried on a conveyor established by rollers (6) into a tempering furnace (1) for the duration of a heating cycle, followed by carrying the glass panels (7) into a tempering station (21), and the glass panels (7) are heated in the tempering furnace (1) by means of bottom- and top-heating radiation elements (2, 3), as well as by bottom- and top-heating convection elements (4, 4a, 4b, 4c, 4, 4a', 4b', 4c', 5) whereby convection air is supplied into the tempering furnace (1). The glass panels' (7) bottom side is heated by means of the bottom-heating convection elements (4, 4a, 4b, 4c, 4', 4a', 4b', 4c'), which are lengthwise of the furnace (1) and define convection heating zones (A, B, C, D, E, F, G, H, I and J) side by side in a lateral direction of the tempering furnace (1). Thus, the convection heating effects of the convection heating zones (A, B, C, D, E, F, G, H, I and J) can be altered relative to each other for profiling the heat transfer coefficient in a lateral direction of the furnace.

IPC: H04W88/18

Granted: 2010-02-16
Abstract: The invention is a Roaming Solution network system (100), the system including a Roaming Server (116), a National Location Register (112), and an 800 number Remote Switching Unit (130). The system is integrated with a standard SS7 type telecommunications network and further coupled to an account based billing and call control platform that allows registered wireless credit limited subscribers to place and receive calls when roaming outside of their Home Provider's network. The invention verifies that the wireless subscriber's account balance is sufficient to place or receive the call, translates the account balance into talk minutes, and monitors the call for talk duration. The Roaming Solution network system is further operable such that if the wireless subscriber exceeds the available account balance, the system tears down the call in the first negative minute and immediately decrements the wireless subscriber's account. If the call is disconnected prior to the account balance being depleted, the invention immediately decrements the wireless subscriber's account and releases the trunks. This Roaming Solution network system is designed to mitigate a Home Provider's exposure to credit risk when providing roaming services to credit limited subscribers.

Abstract: The invention relates to a piston engine comprising a case (25) containing at least two cylinders (3, 4; 5, 6) with inlet openings and outlet openings, which can be opened and closed by means of controllable valves. Each piston (7, 8, 9, 10) can linearly move inside said cylinders (3, 4, 5, 6) in a reciprocating manner. The inventive piston engine also comprises at least one shaft (17), which is rotatably mounted in the case (25), and a transmission device, with which the linear reciprocating motion of the pistons (7, 8, 9, 10) can be converted into a rotational movement of the shaft (17) or the rotational movement of the shaft (17) can be converted into a linear reciprocating motion of the pistons (7, 8, 9, 10). The transmission device comprises a pivotal lever (13; 18) which can be pivoted around a centrally arranged pivot pin (14; 20) mounted in the case (25). A rotatable roller (15; 19) is placed on each of said pivotal levers (13; 18) at both end areas thereof. The rotational axes of the rollers are each perpendicular to the pivot pin (14; 20), and the rollers (15; 19) roll on a track (16) which is joined to the shaft (17) in a fixed manner while extending between both rollers (15; 19), and which is provided with elevations and recesses. Said elevations and recesses are matched to one another such that the rollers (15; 19) located opposite one another on the pivotal lever (13; 18) are in contact with the track, and such that a connecting rod (12), which is connected to the appropriate piston (7, 8, 9, 10), is additionally joined to both end areas of the pivotal lever (13; 18).
